Determine appropriate use of multi-Availability Zones vs. multi-Region architectures

1. Multi-AZ services examples are S3, RDS, DynamoDB. Using multi-AZ can mitigate against the loss of up to two AZs (data centres, assuming there are three. Some regions only have two). This can provide a good balance between cost, complexity and reliability 2. Multi-region services can mitigate failures in AZs or individual regions, but may cost more and introduce more infrastructure and complexity. Use ELB for multi-region failover and resilience, CloudFront
